The Shah function consists of a set of uniformly spaced functions named for this man. That function is the derivative of the Heaviside step function, and is frequently used for its "sifting" property. He developed a notation whose two components can be used to denote the inner product, and he also proposed the existence of a "sea" of negative energy eigenstates. An equation developed by this man describes the relativistic motion of spin 1/2 particles based on 4-component wavefunctions, and is a relativistic generalization of the Schrodinger wavefunction. That equation also suggested the existence of positrons. For 10 points, identify this scientist who proposed the existence of antiparticles.
